Depression can have many types, each with its causes, symptoms and effects on daily life activities. People generally divide depression into two parts, clinical depression which requires treatment and “regular” depression which pretty much anyone can go through. It is important to understand the types of depression because it is referred to as both the symptom of a condition and the condition itself.
Some types of depression may happen because of life events like losing a loved one or experiencing a stressful situation. Research indicates that these forms of depression may improve over time with the support and care from family, friends and healthcare providers.
What is Depression?
Depression is defined as a mood disorder that causes a persistent feeling of depression and sadness. Studies show that 1 in 5 U.S. adults have been diagnosed with depression in their lifetime. It is a condition that affects how a person feels, thinks and behaves and can interfere with their ability to function and carry on with daily life.
Some of the important points related to depression are mentioned below:
- Life events, genetic factors, and chemical imbalances in the brain can trigger it.
- It can last longer and interfere with daily life, work and relationships.
- It can affect anyone regardless of age, gender or background.

DSM 5 Depression Types
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) outlines various types of depressive disorders, their symptoms and causes. The American Psychiatric Association (APA) has created these criteria to help healthcare professionals. All these criteria help in the diagnosis and treatment process.
Healthcare professionals take reference from DSM-5 and follow guidelines to confirm the diagnosis of depression. These guidelines help in the accurate identification of the depression type and help in providing personalized treatment plans tailored to individual needs.
The types of depression categorized under DSM-5 categories are mentioned below:
- Major Depressive Disorder (MDD)
- Persistent Depressive Disorder (PDD)
- Disruptive Mood Dysregulation Disorder (DMDD)
- Premenstrual Dysphoric Disorder (PMDD)
- Medication Induced Depressive Disorder
- Depressive Disorder due to another Medical Condition
- Recurrent Brief Depression
- Depressive Episodes with Insufficient Symptoms

Additional Forms of Depression Beyond DSM-5
There are additional forms of depression beyond DSM-5 that arise due to specific life circumstances, personality traits or unique biological factors. These types do not fit into the standard diagnostic categories but still cause significant emotional distress and functional impairment.
These types can be influenced by external stressors, hormonal changes, seasonal patterns or chronic medical conditions. Healthcare professionals analyze the impact of the condition and provide tailored treatment to help individuals manage their symptoms effectively.
- Situational depression: It refers to symptoms of depression that occur for a short time and may get triggered by stressful life events such as the death of a loved one. It is characterized by changes in appetite, difficulty sleeping and loss of interest in activities.
- Atypical depression: It is a subtype of depression that responds differently from typical depressive disorder. In this condition, people may experience temporary mood improvements in response to positive events but still struggle with persistent depressive symptoms.
- Bipolar depression: It is the depressive phase of bipolar disorder, which is a condition characterized by alternating periods of depression and mania or hypomania. People with this condition may experience extreme sadness, fatigue and loss of motivation.
- Postpartum depression: It is a type of depression that occurs after childbirth. It is more severe than ‘baby blues’. Studies show that it can be caused by hormonal changes, sleep deprivation, emotional stress and genetic factors.
- Seasonal affective disorder: It is a type of depression that occurs at specific times of the year, usually in the fall and winter months when there is less sunlight. Studies show that it can be caused by changes in light exposure, which affects serotonin and melatonin levels and leads to disruptive mood.
- Psychotic depression: It is a severe form of major depressive disorder that includes symptoms of psychosis, such as hallucinations or delusions. These symptoms align with the person’s depressive thoughts such as feeling guilty or worthless.
- Prenatal depression: It is a form of depression that occurs during pregnancy. Studies show that hormonal changes, physical discomfort, stress or a history of mental health conditions may cause it.
- Treatment-resistant depression: It is a form of major depressive disorder that does not respond to standard antidepressant treatments. People with this type of depression experience persistent depressive symptoms despite trying multiple medications or therapies.
